Multiple industry insiders
confided to Business Korea that Samsung is struggling with the yields of its 5nm process. According to the site, fewer than 50 percent of the 5nm chips produced at Samsung's state-of-the-art V1 line at Hwasung Campus are functional.
The V1 Line in Hwaseong, Gyeonggi Province is the world's first dedicated extreme ultraviolet (EUV) line for production of sub-7-nm semiconductors. Samsung Electronics began to operate the line in February 2020.
The most important determinant of a semiconductor company’s business performance is its yield. In general, a semiconductor producer’s yield has to exceed 95 percent.
This is in stark constrast to TSMC. The Taiwanese foundry
recently mentioned that 5nm yields are already better than the yields of its highly successful 7nm process.
